Method of making motorcycle seat frame

Abstract

A motorcycle seat is assembled from a metallic base, a separately formed back rest member of generally L-shaped configuration and a pair of generally L-shaped support rods. These are assembled with the support rods and horizontal portion of the back rest member disposed upon the upper surface of the base and secured thereto, and the rods are also secured to the upstanding portion of the back rest member. Cushion means is disposed upon the base and back rest members and includes a cover extending over the back rest member. The back rest member has a concave transverse cross section and is provided with a multiplicity of recesses in the rearward surface thereof in which buttons disposed on the rearward surface of the cover are substantially disposed.

1.  In a method for making a motorcycle seat, the steps comprising: A. forming a length of metal sheet into a base having a top wall and a sidewall extending generally downwardly therefrom, said base having forward and rearward ends;   B. forming a length of sheet metal into a back rest member having a generally L-shaped configuration defined by a pair of arm portions, one arm portion being of relatively short length and of relatively narrow width and the other arm portion being of substantially greater length and width;   C. forming a pair of support rods into a generally L-shaped configuration, the included angle thereof closely approximating the included angle of the L-shaped configuration of said back rest member;   D. securing said rods and back rest member to each other and to the upper surface of said top wall of said base so that said other arm portion of said back rest member extends upwardly from the rearward end of said base and said one arm portion of said back rest member extends forwardly thereof, said rods extending forwardly along the forward face of said back rest member other arm portion and being secured thereto; and   E. securing cushion means to said base and back rest member including disposing resilient material on the upper surface of said base and the forward surface of said back rest member other arm portion and providing a cover extending over said resilient material on said base and about said back rest member.   
     
     
       2. The method in accordance with claim 1 wherein said back rest member other arm portion is formed so as to have an arcuate transverse cross section with the arc opening forwardly of said seat. 
     
     
       3. The method in accordance with claim 1 wherein said back rest member other arm portion is formed with a multiplicity of generally forwardly projecting bosses defining forwardly opening recesses therewithin. 
     
     
       4. The method in accordance with claim 3 including the steps of providing apertures in said back rest member other arm portion, forming inserts having recesses opening at one end thereof, and inserting the other end of said inserts into said apertures of said back rest member other arm portion to provide said bosses. 
     
     
       5. The method in accordance with claim 3 wherein there is included the step of affixing buttons on the face of said cover by inserting shank portions on said buttons into said recesses of said bosses. 
     
     
       6. The method in accordance with claim 1 wherein said rods and back rest member are secured to each other and to said base by welding.
